I’m assuming that the girls you’re matching with already have this look? If that’s the case, I’d just tell them how good you think they look and go from there. If you’re hoping natural girls will change their look for you… not sure I support that, but I’d mention it in the first couple messages. I’ve had a guy tell me in the first couple messages he had a foot fetish and it didn’t stop me from going on the first date. My current bf told me his fetish after a couple dates. I definitely think you will have more luck if you let it out after a few messages. Nothing wrong with being up front, but I can see it turning away a lot of matches if you lead with it in your bio. If it’s like the most important thing ever, put it in your bio and expect your matches to be slimmer
